AI Technical Summary

Technical Problem

In existing vertical through-cable anchor construction, the anchor cables are heavy, the lowering speed is slow, a large number of workers are required, and the borehole opening is severely damaged, which cannot meet the requirements for rapid construction, especially in underground powerhouses and geological disaster treatment.

Method used

The system employs a combination of traction winches, cable lowering supports, and a transmission frame. Two winches provide traction, and the direction of the anchor cable is changed via a guide shaft and pulleys. The transmission frame serves as a sliding channel to avoid damage, enabling automatic and rapid cable lowering.

Benefits of technology

This enabled the safe and rapid installation of anchor cables, shortened the construction period, reduced the number of construction personnel, and lowered construction costs.

Abstract

The utility model provides a device for quickly and automatically lowering a vertical opposite-penetrating anchor cable, which belongs to the technical field of water conservancy and hydropower engineering and comprises a traction winch, a cable lowering support, a transmission frame, an anti-falling winch and a traction rope. An anchor cable hole is formed in the middle of the bottom of the lower cable support, the conveying frames are arranged on one side of the lower cable support, the traction winch is arranged on the other side of the lower cable support, the anti-falling winch is arranged on one side of the arranged conveying frames, one end of a traction rope is connected with the anti-falling winch, and the other end of the traction rope is bound with the downstream tail end of an anchor cable arranged on the conveying frames. One end of the other traction rope is connected with the traction winch, the other end of the traction rope is bound with the tail end of the upstream side of the anchor cable, and one end of the anchor cable penetrates into the anchor cable hole. The device can prevent the anchor cable from being damaged by an orifice anchor backing plate, a steel pipe and the like, prevents the anchor cable from suddenly falling due to the action of self gravity to generate danger, realizes quick, safe and automatic cable descending, and can effectively shorten the construction period.
